When she ask me(Why do I love her?) what do I say?

Look her in the eye and say "because you make me smile, you are the one that knows me better then anyone, you have a way of brightening my days even when the dark clouds are above me...you are the missing puzzle piece to complete my lifelong puzze, that is why i love you....

Well, why do you love her? I guess you could say because your perfect in every way I wouldn't change a thing. Or because your beautiful, smart, funny, kind, and etc. Use your imagination. Say what she wants to hear. I mean you have to have some reason why you love her. SAY WHAT IS IN YOUR HEART:)

look at her likes shes crazy and ask her why shes asking that question?

i love you because you are you.

sing lee ann rimes (How do i live without you) whisperly
and she,ll understand (turst me it work)

you tell what you really admire on her which most girls do not have and how you feel when you are with her and i think that's easy

Tell her love has no reason to explain. You love everything that belongs to her. If you know the reason exactly, then it means you love a number of things you find in her own personality. This sounds there is still some limit, or border. But since you don't know why you love her, that means you love her for all the things she got, has got, or even will get in the future.
Your love has no limitation, that's why it has no particular reason to just explain.

Be Honest? Hell no! Talk about some thing that happened early in your relationship, tell her she's beautiful and then kiss her deeply.

"And that's why I love you."

tell her she is spacal to you and that you feel as youve nevr feelt befor about her

no need to answer! Just say when you love her because of the sake that you love her

Tell her why you love her....unless you don't love her. Be honest with her.

How the hell do you expect us to tell you, if you can't think of an answer you probably don't really love her. *Answerman, that was the first time I have really laughed out loud from reading someone's answer, other than my own:)

I tossed a coin and you won. But when you say it sort of stand back.
